THOMAS F. KELLY, OF PAWTUCKET, RHODE ISLAND, ASSIGNOR TO HIMSELF ANDTHOMAS F. SULLIVAN, 0F PAWTUCKET, RHODE ISLAND.

TRACK-CLEARER.

Application filed December 4, 1909.

To all whom it may concern:

Be it known that I, THOMAS F. KELLY, a citizen of the United States,residing at Pawtucket, in the State of Rhode Island, have invented a newand useful Improvement in Track-Clearers, of which the following is aspecification.

The object of my invention is to provide suitable means under thecontrol of the motorman, for scraping out and brushing the grooves ofrailroad tracks, whereby the said grooves may be kept clear of any obstrut-ting object or material.

My invention consists in the improved construction and arrangement ofthe parts of the apparatus, as hereinafter set forth.

In the accompanying drawings: Figure 1 represents a side elevationillustrating my improvement. Fig. 2 represents a top view of the same.Fig. 3 represents a front view. Fig. st represents a detail section.Fig. 5 represents a side view of the driving gears.

In the drawing, A represents the forward platform of a trolley car, B,B, the forward wheels of the car, and C the forward axle. The shaft I)is journaled in the bearings Z), L, of the downwardly eXtending hangersE, E, and upon the shaft D is placed the sprocket wheel F, which isdriven from the sprocket wheel G on the axle C, by means of the chain H.To the opposite ends of the shaft D are pivoted the bellcrank levers I,I, the outer ends of which are provided with track clearers J, J, whichare adapted to clear out the grooves a, a, of the rails K, K, the saidlevers I, I, being connected together at their upper ends by means ofthe rod L, from the middle of which connection is made to the lower endof the hand lever M, by means of the Specification of Letters Patent.

Patented Feb. "Z, 1911. Serial No. 531,447.

connecting rod N, and by means of the said hand lever, the clearers J,J, are brought down to the track rails K, K, and are automaticallyraised therefrom by means of the spring P.

The track clearer J is actuated downward by means of a spring 0, asshown in Fig. 1, whereby the said clearer may be enabled to yield to anypositive obstruction without causing an excessive jar upon the handlever M.

Upon the shaft D beyond the bearings Z), 5, of the truck frame, arekeyed the gears c, c, which engage with the teeth of the gears (Z, (l,secured to the inner ends of'the shafts c, c which shafts turn looselyin the journals f, f, of the forwardly projecting arms 2', 2', of thebell-crank levers I, I. And to the projecting outer portions of the saidshafts e, c, are secured the rotary brushes Q, Q, by means of which thetrack rails K, K, are cleared of dirt or rubbish the said rotary brushesand track groove clearers being brought down simultaneously by means ofthe hand lever M and raised simultaneously by means of the spring P.

I claim as my invention:

In an apparatus for clearing out the grooves of a railroad track, thecombination of a spring actuated groove clearer, and a rotary brush,with a spring actuated bell-crank lever, whereby the clearer and brushmay be raised or lowered simultaneously, and a hand lever connected withthe bell-crank lever, substantially as described.
